I think the really cool and compelling thing about math and physics is that it opens up entry to all these hypotheticals - or at least, it gives you the language to talk about them. But at the same time, if a scenario is completely disconnected from reality, it's not all that interesting.
To be off the grid is to be disconnected from most of America's infrastructure without having to cross any border.
For a writer, and particularly a writer of my genre, which is the fantastical, I think that it's to my advantage to feel remote from and disconnected from the world of deal making.
